Abstract

The utility model relates to a touch automatic braking device of automobiles, which comprises a touch reaction line, a micro touch switch, a relay, an electromagnetic valve, a key switch with a lock, etc. The utility model is characterized in that when the forepart of an automobile bumper touch a collision object, the touch reaction line is triggered to make the micro touch switch close, thereby, the normally open contact of the relay connected to a power supply is closed to make the electromagnetic valve connected to the relay operate. Because the iron core of the electromagnetic valve is just connected with the push rod or the draw rod of an automobile braking system, the utility model complete whole braking process. The utility model has the advantages of convenient installation and operation, and can be refitted by the existing automobile.

Description

Touch automatic braking device

The utility model relates to a kind of automobile contacting automatic brake arrangement, particularly a kind of automobile starts the automobile contacting automatic brake arrangement of brake equipment automatically when running into obstacle or bumping against.

In actual life, meet with a street accident through regular meeting, especially in bad weather, it is more frequent that traffic accident occurs, and tends to cause car crash.Statistics from the traffic accident that taken place, and from various tests that traffic management system carried out, what directly cause casualties does not only bump against for the first time, and bump against for the second time often, this strength that bumps against for the second time is great, if utmost point time ground is not braked, can cause than colliding even more serious loss for the first time, even jeopardize personal safety.For the accident that is taken place on the express highway, because automobile driving speed is too fast, the driver is being bumped against under the unexpected situation, owing under the nervous situation of reacting, can cause continuous collision when the utmost point not, till it stops, loses even more serious.Therefore, need a kind of automatic brake arrangement, so that when bumping against, start brake equipment automatically.

The purpose of this utility model just provides a kind of automobile automatic brake arrangement, makes it in an instant start brake equipment automatically in the contact that collides, thereby has avoided the error in the manual operation.

Automatic brake arrangement of the present utility model comprises: touch response line, and little switch that touches, relay, electromagnetism is locked each several parts such as pressing key switch with having.Its principle of work is to touch phase magnetic at automobile to hit thing in a flash, has triggered response line, makes little switch closure that touches, thereby makes the open contact adhesive of the relay that is connected on the power supply, thereby make coupled electromagnetic valve work.Because the electromagnetic valve iron core is connected with the push rod or the pull bar of automobile brake system just, thereby finishes whole braking procedure.Certainly wherein also be provided with lock and pressed key switch etc., when driving needs to start brake equipment automatically, this device has been devoted oneself to work so that guarantee.

Below in conjunction with accompanying drawing and specific embodiment, the description detailed in addition to the utility model.

Fig. 1 is the fundamental diagram of automobile automatic brake arrangement;

Fig. 2 has installed the scheme drawing that touches response line on the anterior projection of the automatic thick stick of automobile;

Fig. 3 is the work scheme drawing that in the automatic brake arrangement electromagnetic valve is installed on the particular location.

Now referring to Fig. 1, it has specifically illustrated the principle of work of automobile automatic brake arrangement.At first, when automobile touches something at the anterior projection of its bumper/spoiler, touch response line interlock micro-switch B thereby make ₁, make the open contact J of relay J ₁Adhesive makes electromagnetic valve Q work, makes the axle with electromagnetic valve Q interlock drive brake equipment, and reaches the effect of autobrake.Certainly, before the relay J adhesive, can also install, press key switch B if any lock with master cock ₂And key door " ON " switch B ₃, so that when not needing to make this device work, can cut off this connected loop.

Fig. 2 has specifically illustrated the scheme drawing that is installed on the fine motion response line on the anterior projection of Federal bumper.As can see from Figure 2, label 1 expression insulcrete face, 2 expression metals, two polar conductors, 3 expression flexible glue skins, 4 expression duroplasts touch bonds, 5 expression body skiies.Little touching in the response line on this position; base plate is made with insulating material; metal two polar conductors 2 are arranged on its face 1; it is established can be straight line or bending is arranged; on lead, cover last layer flexible glue skin or other whippy material; and make itself and lead form a fixed gap; scribble conducting objects in the flexible glue cloth; for protection rubber does not leak outside; can add on the outer layer surface of this flexible glue skin 3 and load onto the rectangular touch bond that duroplasts or other hard material are made, length is not limit, as can 100mm; they are connected to form a line in turn, thereby flexible glue skin 3 is played a protective role.

Recited above also only is concrete an enforcement.The fine motion response line can also be installed on the diverse location according to the particular case of various vehicles, and for example, the side of car or rear portion are perhaps on the appropriate location of car.Final result guarantees that exactly the vehicle braked device in case of emergency can start automatically.

Fig. 3 shows electromagnetic valve and is installed on service condition on the particular location.Number in the figure 6 is brake pedals, the 7th, and push rod, Q are exactly electromagnetic valve, and the 9th, the hollow section iron core, the 10th, iron core goes out end, and the 11st, screw socket, the 12nd, turn to push rod, the 13rd, pull bar.From figure, can be clear that, the push rod 7 that joins with brake pedal be with electromagnetic valve in iron core 9 mutual sockets, being linked to be push rod is one, save and swing to prevent dragging in its interlock process, spring is housed to play buffering in iron core hollow section 9 places,, must selects to use the metal pushrod of nonmagnetic reaction in the iron core hollow section in order to avoid push rod directly clashes, in case in electromagnetic valve when work, make their mutual actions.As can see from Figure 3, automobile is at the needs glancing impact, step on brake pedal 6, drive push rod 7 and

iron core

9 and 10, the interlock brake system, and when in the automobile traveling process, touching object, through process shown in Figure 1, make electromagnetic valve work, the electromagnetic force that passes through to be produced makes

iron core

9 and 10 interlock brake push rods, thereby reaches autobrake.And in brake system of car, can be divided into two big classes, compression air brake, hydraulic braking,, there is the branch of power-assisted and non helping hand device in generation, and wherein pusher structure (specifically can referring to Fig. 3 and above-mentioned description) is arranged specific to brake system, also have Tiebar structure, and this Tiebar structure can be referring to Fig. 3 bottom right, wherein on axle, connect one and turn to push rod 12, with a pull bar 13, its action direction is changed, thereby constitute the braking under the Tiebar structure.

In addition, for the installation site of electromagnetic valve, normally be installed in push rod or pull bar place, thereby form interlock with iron core, and for the extraordinary circumstances of various automobiles, can also be contained on other rational position, this will not be unalterable according to the situation of various cars.

Because the drg difference of automotive use is made manufacturer's difference, so the promotion of electromagnetic valve acting must be determined the thrust kilogram number of its electromagnetic valve by concrete brake system (there are power-assisted or non helping hand in generation for compression air brake, hydraulic braking).

Can believe, use automatic brake arrangement provided by the utility model, can guarantee the safety of people's lives and properties, avoid generation great and continuous serious accident.And install and use all very conveniently, performance is also very reliable, also can reequip easily for existing automobile.
